Résumé
Nanostructured titanium dioxide (TiO₂) is a well-known photocatalyst for wastewater treatment, yet its aggregation in aqueous media often limits its efficiency specially for microorganism’s inactivation [1]. In this study, we explore the potential of earthworm mucus, a natural, protein-rich exudate [2] as a biocompatible stabilizing agent for TiO₂ nanoparticles. Our results demonstrate that earthworm mucus not only improves the colloidal stability and dispersion of nanoparticles, but also enhances its photo-nano-activity against pathogenic bacteria and biofilm formation and stabilization.
